PURPOSE The study aim to identify novel molecular subtypes of ovarian cancer by gene expression profiling with linkage to clinical and pathologic features. EXPERIMENTAL DESIGN Microarray gene expression profiling was done on 285 serous and endometrioid tumors of the ovary, peritoneum, and fallopian tube. K-means clustering was applied to identify robust(More)
Evidence that the insulin pathway may be involved in breast carcinogenesis has increased the interest in dietary factors that influence insulin secretion and resistance. We investigated dietary carbohydrate, fibre, glycaemic index (GI) and glycaemic load (GL) in a prospective study of 324 breast cancers diagnosed in 12,273 post-menopausal women. Although an(More)
BACKGROUND Most persons who are homozygous for C282Y, the HFE allele most commonly asssociated with hereditary hemochromatosis, have elevated levels of serum ferritin and transferrin saturation. Diseases related to iron overload develop in some C282Y homozygotes, but the extent of the risk is controversial. METHODS We assessed HFE mutations in 31,192(More)
UNLABELLED The evidence that mutations in the HFE gene for hemochromatosis are associated with increased cancer risk is inconsistent. The Melbourne Collaborative Cohort Study is a prospective cohort study that commenced recruitment in 1990. Participants born in Australia, New Zealand, the United Kingdom, or Ireland (n = 28,509) were genotyped for the HFE(More)
BACKGROUND Ductal carcinoma in situ represents about 20% of all tumours diagnosed within mammographic screening programs. The natural history of DCIS is poorly understood, as it cannot be observed directly. Estimates of the proportion of DCIS that progress to invasive cancer, as well as factors that may influence progression, are important for clinical(More)
There is concern that exposures to the environmental chemicals polychlorinated biphenyls (PCBs) may contribute to breast cancer risk. An individual's susceptibility to the effects of PCBs may be partially determined by polymorphisms in the gene encoding the biotransformation enzyme cytochrome P450 1A1 (CYP1A1). PCB exposure induces CYP1A1 activity, and PCBs(More)
OBJECTIVE To evaluate the effect of dietary folate intake on the relation between alcohol consumption and breast cancer risk. DESIGN Prospective cohort study. SETTING Melbourne, Australia. PARTICIPANTS 17,447 Anglo-Australian women resident in Melbourne, aged 40-69 years at recruitment in 1990-4, and followed up until 31 December 2003. MAIN OUTCOME(More)
Increasing cervical screening coverage by reaching inadequately screened groups is essential for improving the effectiveness of cervical screening programs. Offering HPV self-sampling to women who are never or under-screened can improve screening participation, however participation varies widely between settings. Information on women’s experience with(More)
OBJECTIVE The progestagenic milieu of pregnancy and oral contraceptive use is protective against epithelial ovarian cancer. A functional single nucleotide polymorphism in the promoter of the progesterone receptor (+331A) alters the relative abundance of the A and B isoforms and has been associated with an increased risk of endometrial and breast cancer. In(More)
BACKGROUND Australia introduced a human papillomavirus (HPV) vaccination programme with the quadrivalent HPV vaccine for all women aged 12-26 years between 2007 and 2009. We analysed trends in cervical abnormalities in women in Victoria, Australia, before and after introduction of the vaccination programme. METHODS With data from the Victorian Cervical(More)
